A fast breeding method of kiwi grafting seedlings

Abstract

The invention relates to the technical field of agriculture, in particular to a rapid breeding method for grafted seedlings of kiwifruit. The breeding method of the present invention includes the steps of selection of rootstock seedlings, cultivation of rootstock seedlings, selection of scions, grafting of scions, management of grafted seedlings and the like. The method has the following advantages: 1) it is easy to operate and master; 2) it shortens the breeding time of seedlings, improves the quality of seedlings, and saves management costs; 3) is conducive to cultivating robust seedlings, shortens the period of garden construction, and realizes early benefits of early gardening. The method can also provide reference for the seedling breeding methods of other fruit trees, especially the fruit trees that are bred with seedlings by grafting.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a rapid breeding method for grafted seedlings of kiwifruit. Background technique [0002] my country is the world's largest producer of kiwifruit, ranking first in the world in terms of cultivation area and total output. However, there is still a big gap between my country's kiwifruit industry and New Zealand, Italy, Chile and other industrial powerhouses, which is mainly reflected in the output per unit area. The rate of fruit and commercial fruit is low, and the unit price is also low, resulting in significantly lower benefits per unit area than other countries. However, there is a strong demand for kiwifruit in the domestic consumer market. The number of kiwifruit imported in my country has been maintained at more than 120,000 tons all year round, and it is still increasing every year. The main reason is that the quality of seedlings in the domestic kiwifruit industry is g...

Problems solved by technology

Although the first method has a higher survival rate of seedlings, for the establishment of kiwi fruit orchards, the growth of seedlings takes a long time, plus the one-year growth of rootstocks, it takes at least 3 years to complete the gardening operation. Years to form a small amount of production

Although the second method can save one year, it requires a more stringent and refined management plan for the seedlings after grafting, so that the rootstock can take root and the scion can survive. Therefore, this method of seedling breeding has higher technical requirements. It is difficult for ordinary growers to quickly grasp, resulting in the generally low survival rate of the second seedling raising method

[0004] At present, our country has not established a complete and standardized kiwifruit seedling breeding technology system. For the breeding of grafted seedlings, we often only pay attention to the survival rate and ignore other quality indicators such as roughness and whether there is infection by bacteria.
